Redeemable Noncontrolling Interests The holders of equity interests in certain of the Company's subsidiaries have rights ("Put Rights") that may be exercised on varying dates causing the Company to purchase their equity interests through fiscal 2025. The Put Rights, all of which relate either to common shares or membership interests in limited liability companies, provide that the cash consideration to be paid for their equity interests (the "Redemption Amount") be at fair value or a formula that management intended to reasonably approximate fair value based solely on a multiple of future earnings over a measurement period.

Redeemable at fair value |  |  | $81,495 |  |  |  | $85,574 |

As discussed in Note 2, Acquisition, the Company, through the FSG, acquired an 80.1% equity interest in A2C in April 2017. As part of the purchase agreement, the Company has the right to purchase the noncontrolling interest in the subsidiary over a two-year period beginning in fiscal 2022, or sooner under certain conditions, and the noncontrolling interest holder has the right to cause the Company to purchase the same equity interest over the same period. Pursuant to the purchase agreement related to the acquisition of an 80.1% equity interest in a subsidiary by the FSG in fiscal 2011, the holders of the 19.9% noncontrolling interest in the subsidiary exercised their option during fiscal 2016 to cause the Company to purchase their interest over a two-year period ending in fiscal 2017. During the second quarter of fiscal 2017, the Company acquired the remaining 9.95% noncontrolling interest in the subsidiary effective March 2017. The purchase price of the redeemable noncontrolling interest acquired was paid using cash provided by operating activities.
